How to Make a Long Range Wireless Antenna

by Adam Quinn

If you live in a rural area or on a large plot of land, you may need a long range wireless antenna to access your town's free Wi-Fi signal or distribute your own wireless connection around your property. To maximize signal strength at a distance, a "cantenna" wireless antenna design is a long range option for the budget conscious builder.

Step 1

Measure and mark 1 13/16 inches up from the closed end of the can.

Step 2

Drill a 1/4-inch starter hole through the can at the mark. Then widen this hole with a 5/8-inch bit.

Step 3

Slide the N connector through the hole, copper wire first. Bend back the hole in the can with pliers if the N connector will not fit through. Then tighten the bolt ring of the N connector on the inside of the can using the pliers.

Step 4

Adjust the N connector so the 3/16-inch copper wire radiator is vertical and is 1 12/16 inches from the back of the can.

Connect the cantenna using a pigtail wire fitted with a male N connector and a connector particular to your wireless card.


  • To extend the range, attach the cantenna to the feed point of a satellite dish.

Items you will need

  • Tin can, 40 oz.
  • N-type connector, female, screw-on mount with 2.4 GHz copper wire radiator
  • Power drill and 1/4- and 5/8-inch metal-cutting bits
  • Pliers
  • Measuring tape
  • Permanent marker
